1. Product use: Our THT-TNP-type neutral grounding protection devices are designed to 110kV, 220kV and 330kV power transformer neutral circuits, to achieve switching between such two operating modes as the transformer neutral grounding and nor-grounding, and avoid damages to transformers due to voltage rise of the transformer neutral points resulted from system failures or other reasons.

Construction:

1. THT-TNP type Neutral Grounding Protection Device is assembled by disconnecting switchLightning arresterInterval current transformer, featuring compact size, convenient installation and high reliability.

2. The mounting brackets adopt seamless steel pipes, featuring better stability and more beautiful appearance if it is required.
